Around here dogs in certain stores isn't uncommon, I have seen lots of dogs in tractor supply, rural king, pets mart and jacks aquarium just to name a few, there all dog friendly stores. I understand the idea of animals going wherever the owner goes, I believe it's good for the animals to take a ride now and again, all animals I see in those stores are always well behaved, ignore other people unless approached ext and I personally have had at least one dog in every store I mentioned, rather than leaving the dog in the car, I knew the store was pet friendly so what the heck. I have seen windows smashed because a animal was in the car alone, one time this girl had a pet carrier in her SUV, and someone smashed the window thinking there was a animal inside, the law was called and the people just apologized, never heard if they paid for a new one or not.
When a dog I had was 11 weeks old (mini pin) i didn't want to leave him at home alone so I brought him with me when I rode along with my sister to AT&T (I was the account holder and had to be there to activate her BF to my family plan) we went to 1 AT&T store and 2 Verizon stores, it was about 95 outside and I held the dog the entire time I was in the stores because they were not pet friendly stores and I didn't want it to be an issue, it never was, no employees asked me to leave, no other customers complained, the dog just looked around very quietly and life went on, I had the occasional person stop and want to pet the dog which i kinda feel is annoying but I let them, usually kids and women.
Unless the animal is causing trouble and badly behaved I can care less if I see one in a store. I have never seen one in a stroller though or dressed up, that would be a new one for me.
